Early symptoms of nasopharyngeal carcinoma (NPC) can often be deceptive and confusing. Most patients with nasopharyngeal carcinoma present at an advanced stage with metastatic cervical nodes present at the time of diagnosis. A deep neck abscess as the presenting feature has not been reported. We report two cases of nasopharyngeal carcinoma which presented with retropharyngeal abscesses and persistent lymphadenopathy. These two patients illustrate that refractory lymphadenopathy, despite adequate treatment of the associated infection, should prompt a search for underlying disease. The relationship between nasopharyngeal carcinoma and retropharyngeal abscess is discussed.

Alloplastic nasal augmentation with silicone elastomer (Silastic) is popular in areas of Asia. Although the silicones are bio-inert, they have been implicated in a number of adverse reactions after implantation. We report our experience of three patients who presented with late complications after nasal augmentation using Silastic implants. The mechanisms of implant failure are proposed. It is advised that this material should only be used on an individual basis in carefully selected cases.

Congenital laryngeal cysts are a rare cause of neonatal upper airway obstruction which may lead to serious morbidity and mortality if diagnosis and treatment are delayed. We reviewed our experience with nine patients over a six-year period. The annual incidence of this condition was 1.82 per 100,000 live births. The diagnosis can be confirmed safely by flexible laryngoscopy before definitive surgery is contemplated. Contrary to other studies, we found that endoscopic removal of cysts can achieve an effective cure without recurrence. Endoscopic deroofing is as effective as endoscopic excision but is technically simpler and thus is recommended as the treatment of choice.

Malignancy is a major cause of vocal fold paralysis. Nevertheless, metastatic disease at the brainstem leading to high vagal paralysis is rarely encountered. We illustrate an unusual case of unilateral vocal fold paralysis caused by dural metastasis directly compressing on the nucleus ambiguus. The median position of the paralysed vocal fold is inconsistent with the Wagner and Grossman theory predicting the location of the lesion.
